To all zbitom'it may concern Be It knowmthat'we, ENNIS H. THOMP- I ountyof: lVestmoreland and State of Pennsylvania, have invented anew anduseful ilmprovement ;in Capping'Ofi" ikpparatusfor-Glass Cylinders, ofwhich the followiiig is aft-11, clear, and exatzt description,reference-being had to the accompanying. drawings, forming cation, in'which-- v p F igure 1 is a side elevatiqn showing one part of thisspecifiform ofour invention; Fig. 2 is a partial n so .7 side elevationion a larger scale; Fig. 3 isan end elevation of the same; F ig. l isacross section on the-line IV-IV of Fig 1; Figs. 5 and 6 aredetail viewshereinafter referred to Fig. 7 is an end elevation showing a. modifiedform; and F igh8 is'a elevation of the fohm of Fig. 7

ur invention relates to electrical crackofiapparatus forsevering longcylinders into suitable lengths for opening and fiat- I tening,

The object'of the invention is-to provide -simple-and eifectivemechanismfor this purose which may be operated byunskilled lahor, may be used ondifferent sized cylinders, a'ndWill-do away with the wrapping of theelectric heating wires by hand and the need of rotating-the cylinder orcrack-off device.

'- In the drawings, referring to the forms of Figs. 1 to 6, inclusive,2, 2 represent the longitudinal IE-beams of a truck structure worm 10,on shaft 11, which may be'rotated vhaving transverse members 3, mounted.on

end wheels 4, at andintermediate wheels 5. The intermediate wheels areinsulated from the beamsby'insulated brackets, shown at 6 in Fi 4:, andact to receive electric current,

fromihe'third rail shown at 6?; while the end wheels are groundedthrough their rails. This truck frame-is provided with a pair of shafts7, 7, 'extending within stationary hearings in standards 8 on the truck.These shafts have intermeshing pinions '9, 9 at their ends and one ofthem is provided with an intermediate worm wheel actuated by either byhand or by suitable motor ordriving connections. In the formillustrated,

purpose. Secured to these shafts atsuitable intervals apart are thearc-shaped or semicircular arms 13, arranged in palrs, -one sepin 21, towhich the conductor partial side inwardly toward pulley 18,

.the cylinder will drawudo wn operation.-

cured! to each sh'aft. Rotation of the shafts will simultaneously swingthese, arms tosulating material, in which is pivoted a wheel 18' overwhich extends the electric heating.wire-19.-' Each carrier-17 issupported upona curved leaf spring 17*, secured to the arm 13 at 20.This springnormally li olds the parts in the position shown in Fig. 3-.r The guide tube 14: is slotted along one side and through this slotprojects. the

22 is fixed, th s conductor. extending from snap a switch 23 on"the arm.One end of each wire 19 is secured to the arm at, 24, the wire thence.extendingoutwardly' over a grooved wheel or pulley :25 on spring-arm26, and thence, the end of the arm to the whence it extends across theapparatusto the similar wheel of the other arm, thence over this pulley25 and to the fixed'point 24.

The currententer-s through amain feed wire-27, from the intermediatewheels, and thence through branches 28 to, rheostats 29, one for eachelectric heating wire. From this rheostat; the current passel; throughwire 30 along one of the swing arms to the snap switch 23 thereon, andthence lJQ'thB sliding. rod which conducts through the wheel supportsand wheel 18 to the movable wire 19; thence through the'wire to itsother :end'; thence to the other sliding rod and will be wrapped aroundthe glass cylinder shown at A, the parts then assuming theposition-shown in Fig. 4:. During this action, the pull of the wirewrapping around the rods or plungerswithin'the tubes14 against theaction of the inner leaf springs, the parts then being ready for thecracking-off or capping ThecylinderjA is preferably carried on rollers31,; 'Whichare shown S mounted in sets of'two air -me oneach side ofeach "ried out the same as'before and thereafter' apparatus,

pair of swinging arms. These pairs of rollers are shown as mountednstationary frame supports 32. -These frame supports are shown asadjustable along the I-beam to the tr'unkg beingadjustably secured byclamps 33 (Fig. 6) and we have shown them.

as tied together on opposite sides ofthe central longitudinal axis ofthe machine.

In using the apparatus, the parts being in the position shown in Fig. 3,the cylinder is laid on the successive sets of rollers 31. The i handwheel 12 is then actuated to'sWing the arc-shaped arms upwardly andinwardly toward each other, thus wrapping'the successive heat wiresaround the cylinder. The parts then assume the position shown in Fig. iand the operator or operators,

rheostats and snap switches, can turn on the current simultaneously'orsuccessively for heating the different portions-of the cylinderincluding the end or-cap portion. current may then be turned off, therollers cracked apart in the usual way and the arms swung back to their.original position. -'I he apparatus may bemoved' on its supporting railsto the point-desired for useand is'selfcontained.

In Figs. 7 and 8 we show another form of f the invent on which may beemployed with a stationary horse or supportfor the cylinder. This formis similar to the form. of. Figs; 1

to 6 inclusive, except that'the glass cylinder-j is supportedindependentlyv of the crack-01f to lift the cylinder off from the-horseand on to these rollers as the swing arms are-swung up to theiroperating position. In this form, 3i indicates pipe standards havingdiagonals 35, through which extend the overhang ing supports 36,-covered-with suitable. sectional sleeves 37v of asbestos material. I

The cylinder A rests on the overhanging arms 36 at a suitable height,'so that our cracking-oft apparatus may be moved under it, as shown inFig. 7. In'this form, the supporting rollers '31 are carried on theswinging arms 13 Consequently,

or other suitable each other, the wheels 31 will strike the glasscylinder and lift it away-from the time, the wires will be 4 wrappedaround the cylinder at the sepaw horse. At the same rated points, as inthe first form, until the parts assume the position shown in dottedlinesin Fig. 7. Tlieoperation is then carthe arms are swung down,thusallowing the cylinder to drop back'on the overhanging supports of thestationary horse.

' Theadvantages of'our invention will be obvious to those skilled in theart, since the hand wrapping of the-wiresaround the cylinder is obviatedand the craclnng-oft opera;
